Dedicated Servers :It is usually a server assigned only to one user, or just a few websites, usually for the sole use by one company. The cost of a dedicated server is very higher than that of a shared hosting account. Dedicated server provides, you the access to the core administrative functions of the server.With many dedicated server plans offered by hosting companies, you are pretty much on your own where technical support is concerned. If you don’t have an IT staff or a server administrator to provide support, you may want to find a person to help you manage your dedicated server. Many hosting companies that offer dedicated server plans also offer “per issue” support, meaning that you will pay a certain amount, usually an hourly fee, for technical support issues. Some dedicated server plans have optional “support tickets” that you can purchase in advance.And there are also many hosting provider who provides fully manged private servers,they do not charge extra for managing the server.With a managed dedicated plan, you get a dedicated server and the hosting company also provides comprehensive support like you usually find in a shared hosting plan. This is a good alternative for companies that don’t have an IT staff or a server administrator and don’t want to get involved at all in the technical aspects of running a server. The price for a managed dedicated server is usually higher than for an unmanaged dedicated server plan as you’re getting technical support included.

Shared Hosting : It is an account on a web server that hosts other shared accounts. The number of accounts on one shared server can vary widely; some servers host a only few hundred, while others have thousands of websites hosted on one single server. Hosting your website on a shared server is a workable solution for many small businesses, as shared hosting accounts are priced very much lower than a dedicated servers. Shared web hosting accounts have limited access to the core administrative functions of the server. Many webhosting companies offers comprehensive technical support for users of shared hosting plans. Complete technical support is usually included in the price of your account plan.

Note:Whatever type of web hosting plan you choose, make sure that the plan you’ve chosen fits your needs.

1) Basic Config File Editing

Before starting you must make a backup of your /etc/my.cnf file by simply typing copy “cp#” /etc/my.cnf /etc/my.cnf.back , and after that you can perform the following via SSH:

pico /etc/my.cnf
Now replace the current existing lines:

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
skip-locking
skip-innodb
query_cache_limit=8M
query_cache_size=256M
query_cache_type=1
max_connections=500
max_user_connections=10
interactive_timeout=20
wait_timeout=20
connect_timeout=6
thread_cache_size=128
key_buffer=16M
join_buffer=1M
max_allowed_packet=16M
table_cache=1024
record_buffer=1M
sort_buffer_size=2M
read_buffer_size=2M
max_connect_errors=10
# Try number of CPU’s*2 for thread_concurrency
thread_concurrency=4
myisam_sort_buffer_size=64M
#log-bin
server-id=1

[mysql.server]
user=mysql
basedir=/var/lib

[safe_mysqld]
err-log=/var/log/mysqld.log
pid-file=/var/lib/mysql/mysql.pid
open_files_limit=8192

[mysqldump]
quick
max_allowed_packet=16M

[mysql]
no-auto-rehash
#safe-updates

[isamchk]
key_buffer=32M
sort_buffer=32M
read_buffer=16M
write_buffer=16M

[myisamchk]
key_buffer=32M
sort_buffer=32M
read_buffer=16M
write_buffer=16M

After that hit CTRL + X to exit and save the file

Once it is done Edit the httpd.conf:

pico /usr/local/apache/conf/httpd.conf (or wherever your httpd.conf is located)

Set “Timeout” value to “Timeout 300″
Change “KeepAlive on” to “KeepAlive off”
Set “MinSpareServers” to “MinSpareServers 8″
Set “MaxSpareServers” to “MaxSpareServers 13″
Set “MaxRequestsPerChild” to “MaxRequestsPerChild 50″
Set “HostnameLookups” to “HostnameLookups Off”

CTRL + X to exit and save the file

Restart Apache and MySQL with:
service httpd restart
service mysql restart OR service mysqld restart

People may need to restart the services with /etc/rc.d/init.d/httpd restart and /etc/rc.d/init.d/mysql restart

The above changes can be modified and configured according to your server’s needs .

2) Installing Mod_Perl

What is Mod_Perl?

mod_perl gives you a persistent Perl interpreter embedded in your web server. This lets you avoid the overhead of starting an external interpreter and avoids the penalty of Perl start-up time, giving you super-fast dynamic content.

YOu should Run these commands via SSH:

wget http://perl.apache.org/dist/mod_perl-1.0-current.tar.gz

tar zxvf tar zxvf mod_perl-1.0-current.tar.gz

cd mod_perl-1.29

perl Makefile.PL

If in case you face any errors about missing dependencies like CGI.pm, LWP::UserAgent & HTML::HeadParser which is required by mod_perl you may install them with:

perl -MCPAN -e shell
install HTML::HeadParser

If you had to install any dependencies you must re-run “perl Makefile.PL”. Back to setting up mod_perl, after perl Makefile.PL run:

make
make install

Now, you have just installed mod_perl. Restart Apache with:

service httpd restart
OR
/etc/rc.d/init.d/httpd restart

3) Install Turck MMCache for PHP

What is Turck MMCache for PHP?

Turck MMCache is a free open source PHP accelerator, optimizer, encoder and dynamic content cache for PHP. It increases performance of PHP scripts by caching them in compiled state, so that the overhead of compiling is almost completely eliminated. And it also uses some optimizations to speed up execution of PHP scripts. Turck MMCache typically reduces server load and increases the speed of your PHP code by 1-10 times.

Turck MMCache requires: apache 1.3, mod_php 4.1, autoconf, automake, libtool, m4. You should already have most of these on your server if not use the “apt-get install ” command to get them installed. I

To install Turck MMCache, perform the following commands via SSH:

wget http://aleron.dl.sourceforge.net/sou…e-2.4.6.tar.gz

export PHP_PREFIX=”/usr”

$PHP_PREFIX/bin/phpize

./configure –enable-mmcache=shared –with-php-config=$PHP_PREFIX/bin/php-config

(You must specify the real prefix where PHP is installed in the “export” command. It may be “/usr” “/usr/local”, or something else.)

make

make install

Turck MMCache can be installed both as Zend or PHP extension, so you need to edit your php.ini file (usually /etc/php.ini).
To install as Zend extension:

zend_extension=”/usr/lib/php4/mmcache.so”
mmcache.shm_size=”16″
mmcache.cache_dir=”/tmp/mmcache”
mmcache.enable=”1″
mmcache.optimizer=”1″
mmcache.check_mtime=”1″
mmcache.debug=”0″
mmcache.filter=”"
mmcache.shm_max=”0″
mmcache.shm_ttl=”0″
mmcache.shm_prune_period=”0″
mmcache.shm_only=”0″
mmcache.compress=”1″

To install as PHP extension:

extension=”mmcache.so”
mmcache.shm_size=”16″
mmcache.cache_dir=”/tmp/mmcache”
mmcache.enable=”1″
mmcache.optimizer=”1″
mmcache.check_mtime=”1″
mmcache.debug=”0″
mmcache.filter=”"
mmcache.shm_max=”0″
mmcache.shm_ttl=”0″
mmcache.shm_prune_period=”0″
mmcache.shm_only=”0″
mmcache.compress=”1″

You may need to copy the mmcache.so file to the directory specified to the above paths in the configuration entries.

Create the cache directory:
mkdir /tmp/mmcache
chmod 0777 /tmp/mmcache

Restart Apache with:

service httpd restart
OR
/etc/rc.d/init.d/httpd restart

4) Tuning sysctl.conf

What sysctl.conf?

The sysctl.conf of a server is something that is seldom optimized for performance. You can get a tremendous boost in throughput by adjusting these settings. This configuration has been written by Steve from Rack911. I have applied this configuration to servers ranging from Celeron 1.7Ghz to Dual Xeon 2.8Ghz servers, and on the whole, the load on each lowered after making the changes.

First make a backup of your old /etc/sysctl.conf file by running the following command, logged in as root:

cp /etc/sysctl.conf /etc/sysctl.conf.bak

Now enter:
pico /etc/sysctl.conf

and replace the contents of the file with the following:

# Kernel sysctl configuration file for Red Hat Linux
#
# For binary values, 0 is disabled, 1 is enabled. See sysctl(8) and
# sysctl.conf(5) for more details.

# Disables packet forwarding
net.ipv4.ip_forward=0

net.ipv4.conf.default.accept_source_route = 0

# Enable IP spoofing protection, turn on source route verification
net.ipv4.conf.all.rp_filter = 1
net.ipv4.conf.lo.rp_filter = 1
net.ipv4.conf.eth0.rp_filter = 1
net.ipv4.conf.default.rp_filter = 1

# Disable ICMP Redirect Acceptance
net.ipv4.conf.all.accept_redirects = 0
net.ipv4.conf.lo.accept_redirects = 0
net.ipv4.conf.eth0.accept_redirects = 0
net.ipv4.conf.default.accept_redirects = 0

# Enable Log Spoofed Packets, Source Routed Packets, Redirect Packets
net.ipv4.conf.all.log_martians = 0
net.ipv4.conf.lo.log_martians = 0
net.ipv4.conf.eth0.log_martians = 0

# Disables IP source routing
net.ipv4.conf.all.accept_source_route = 0
net.ipv4.conf.lo.accept_source_route = 0
net.ipv4.conf.eth0.accept_source_route = 0
net.ipv4.conf.default.accept_source_route = 0

# Enable IP spoofing protection, turn on source route verification
net.ipv4.conf.all.rp_filter = 1
net.ipv4.conf.lo.rp_filter = 1
net.ipv4.conf.eth0.rp_filter = 1
net.ipv4.conf.default.rp_filter = 1

# Disable ICMP Redirect Acceptance
net.ipv4.conf.all.accept_redirects = 0
net.ipv4.conf.lo.accept_redirects = 0
net.ipv4.conf.eth0.accept_redirects = 0
net.ipv4.conf.default.accept_redirects = 0

# Disables the magic-sysrq key
kernel.sysrq = 0

# Decrease the time default value for tcp_fin_timeout connection
net.ipv4.tcp_fin_timeout = 15

# Decrease the time default value for tcp_keepalive_time connection
net.ipv4.tcp_keepalive_time = 1800

# Turn off the tcp_window_scaling
net.ipv4.tcp_window_scaling = 0

# Turn off the tcp_sack
net.ipv4.tcp_sack = 0

# Turn off the tcp_timestamps
net.ipv4.tcp_timestamps = 0

# Enable TCP SYN Cookie Protection
net.ipv4.tcp_syncookies = 1

# Enable ignoring broadcasts request
net.ipv4.icmp_echo_ignore_broadcasts = 1

# Enable bad error message Protection
net.ipv4.icmp_ignore_bogus_error_responses = 1

# Log Spoofed Packets, Source Routed Packets, Redirect Packets
net.ipv4.conf.all.log_martians = 1

# Increases the size of the socket queue (effectively, q0).
net.ipv4.tcp_max_syn_backlog = 1024

# Increase the tcp-time-wait buckets pool size
net.ipv4.tcp_max_tw_buckets = 1440000

# Allowed local port range
net.ipv4.ip_local_port_range = 16384 65536

CTRL + X to exit and save the file

To make your changes take effect immediately, type this command:
/sbin/sysctl -p

You can easily watch your server load by entering “uptime” command via SSH.
